Vedclass · Answer

(D) Statement $D$ is incorrect because respiration in adult amphibians primarily occurs through lungs and skin. While larval stages (tadpoles) respire through gills,adult amphibians do not possess gills. Therefore,the statement implying that all amphibians respire through gills,lungs,and skin simultaneously is inaccurate.- Cyclostomes (like lampreys) are indeed marine but migrate to fresh water for spawning.- Arthropods constitute the largest phylum,comprising over two-thirds (not just one-third) of all named species,but the statement 'over one-third' is factually true as it is a subset of the total.- Platyhelminthes (flatworms) are predominantly endoparasites in animals.
